Bad behavior is universal. The local Ford dealership has offered free use of their J1772 240 volt charging connection for years that is between their showroom and shop doors. Now there is a No Tesla charging except on weekends sign up. From time to time a Telsa would be left plugged in overnight and still be there unattended during business hours the morning. The nice thing about a Tesla charging on a J1772 charge station is they can not lock the charging cord to their car but just their Tesla provided J1772 adapter.
I only use the free ones in the area to insure I can get home with a margin of safety range so adding 10-20 miles does not take long when the level of charge is very low. I was given permission to use these free chargers before I used them and most often I just sit in the car and I never lock the charging cable to be on the safe side should they have a business need for the chargers. One can reach the spot in front of the charging station and the parking spot on either side. The utility company's charger is in the front parking lot and they do have some F-150 hybrids and one manager had a Leaf at one time I was told. The cord on that charger will reach 5 parking spots. When I use that charger I put a $2 charge on my meter base when I get the car to my home charger.
The EA charges at Walmart with the 50 amp CHAdeMO is $0.21 per minute of use with 10 minutes of grace after you get the text the charging is complete. After 10 minutes of grace your card starts being charged at the rate of $0.40 until you physically remove the charging cable from your EV.
If I had to use my Telsa Tap with an Tesla Destination charger I would lock it if I had to leave the car due to its cost but would want to go down and move away after getting the charge that I needed for the next day in case someone checked in late that was low on charge. Some could still unplug the Tesla Destination charger from my Tesla Tap and start using it.
Again for about 99% of the time I do not have a need for charging stations because it is such a no brainer to charge while I sleep at home. I think a lot of people was like me a few months ago and think public charging stations are needed for daily commutes. That seldom is the case I now understand.
There was no way I was going to learn the ropes of EV ownership and usage without putting money on the line to get an EV.
Now I never plan to be without an EV going forward. By the time there are $30K EV's with 300 miles of range charging stations will not be of much concern to most which is not the case with a range of 75 miles today.
